Suppose a car that has a mass of 1165.4 kg is about to crash into a wall traveling at 19.7 m/s. The car crashes forward with the wall for a total 1.7 seconds. What is the force the car put on the wall?
Note this is not a realistic example like in the video.
Hint; think of the impulse equation.

only one applies and that is (A)

Step-by-step explanation:

You want to test the claim that the relationship between Length of Year and Distance from Sun is linear.

Since length of year depends on distance from sun, length of year is the dependent variable while distance from sun is the independent variable.

If we wish to express the linear relationship in the form of an equation, we have:

LOY = f(DFS)

That is, Length of year is a function of Distance from sun

Now, if you could get data on both variables, the first thing you should do before deciding whether to proceed with the hypothesis test is:

(A) Examine a scatter plot to see whether there is a linear relationship between the two variables.

A scatter plot is a diagram showing the points where corresponding X and Y values of the given data meet.

Where X is the independent variable and Y is the dependent variable.

After all the points of corresponding X and Y values have been located on the graph, you can draw a line connecting all the points and then another line from the first dot to the last.

If the dots move in a particular direction (e.g. upwards or downwards), there is a linear relationship between the variables.

The hypothesis test to be carried out afterwards (the test to determine whether there is a linear relationship between the variables, in the population) is the TEST OF CORRELATION.

Good luck.
